10.2.1.3 Meinberg GNS-UC Receiver (GPS and Galileo)
microSync - GPS/Galileo based Time Synchronization for Stationary and Mobile Applications using Mein-
berg Antenna/Converter Technology
The microSync unit has a special receiver concept which is able to capture GPS and Galileo signals using
a standard Meinberg antenna/converter unit. The configuration supports to select one of these to be used
exclusively or the combination of the sources.
The receiver is capable of operating during high speed movement and delivers reliable and highly precise
synchronization solutions in stationary installations and on fast moving vehicles, such as aircraft, ships or trucks.
The variety of inputs/outputs makes this receiver the first choice for a broad range of applications, includ-
ing time and frequency synchronization tasks and the measurement of asynchronous time events.
The microSync with its integrated GNSS receiver provides accurate time with ultimate precision both in sta-
tionary and mobile environments by supporting long antenna cables because of the Meinberg antenna/converter
technology.

Description
The microSync offers satellite based time synchronization at the highest accuracy standards for fixed or mobile
applications. It is suitable to be deployed in data centers or on board of cars, trucks, aircrafts, ships and other
moving platforms. The satellite receiver can determine its position even at a maximum acceleration of up to 4
g, at a maximum speed of 500 m/s and at an altitude of up to 18,000 meters.
The microSync is used to manage high accurate timing and measurement tasks. The board is able to gen-
erate fixed and programmable standard frequencies with very high accuracy and stability. Various oscillator
options allow to meet different requirements concerning the accurracy of the outputs in the most cost efficient
way. The pulse generator of the GNS181-UC generates pulses per second and per minute. As an option four
programmable outputs are available. The pulses are synchronized to the UTC second.
The module provides two inputs for measurement of asynchronous time events. These capture events can
be read via a serial interface. The board uses a binary interface protocol to receive configuation parameters
and exchange status information with external equipment via its RS-232 interfaces.
MRS capability
The oscillator of the GNS181-UC can be disciplined by an external reference source (e.g. 1PPS, 10 MHz, IRIG,
PPS + String).
